dc.description.abstract | High temperature is one of the most detrimental abiotic stresses in tomatoes. Many studies
highlighted that even small increases in temperature can alter the plant reproductive system, causing a
significant reduction in tomato yield. The aim of this study was to exploit the phenotypic and genomic
variations of a tomato landrace collection grown at high temperatures. Fifteen genotypes were
selected as the best performing in two experimental fields. The selection was based on six yield-related
traits, including flower earliness, number of flowers per inflorescence, fruit set, number of fruit per
plant, fruit weight and yield per plant. In order to identify markers targeting traits that could be highly
influenced by adverse climate conditions, such as flowering and fruit setting, an association mapping
approach was undertaken exploiting a tomato high-throughput genomic array. The phenotypic
variability observed allowed us to identify a total of 15 common markers associated with the studied
traits. In particular, the most relevant associations co-localized with genes involved in the floral
structure development, such as the style2.1 gene, or with genes directly involved in the response to
abiotic stresses. These promising candidate genes will be functionally validated and transferred to a
cultivated tomato to improve its performance under high temperatures. | ca |
